Quads SP Free is a limited Single Player only variant of Quads graphically re-sized for the iPhone and iPod touch. Other than small re-positioning and sizing of components, the gameplay is exactly the same as our tablet based versions. If you haven't seen either the description of Quads MP HD or Quads SP HD we describe the game below.
Quads uses the 7 standard (I, L, J, S, Z, T, and O) tetromino pieces falling from 4 different directions toward a square center Drop Zone. The twist with Quads is, players must arrange the randomly falling pieces into complete Quadrilaterals (Squares or Rectangles) centered around the Drop Zone in order to clear any tetrominos from the game board. For added challenge, when levels are cleared, the game randomly chooses whether to speed up the standard movement of tetrominos, or increase the size of the center drop zone (shinking the fall area pieces have, and increasing the minimum size of the Quads that must be built). Beyond these challenges, a player may choose to have multiple tetromino pieces falling simultaneously.
Figure 1 shows Quads SP Free being played in marathon mode level 1. The center drop zone is 8 x 8, and the speed level is 1. Only one piece has been selected to fall simultaneously, with ghosts enabled, future pieces (and the hold location) enabled.
